I have found a solution by myself. I use the PDANet tool to find the driver automatically.

Sure, you just call it from within the SP, there's no special syntax.

Ex:

   PROCEDURE some_sp
   AS
   BEGIN
      some_other_sp('parm1', 10, 20.42);
   END;

If the procedure is in a different schema than the one the executing procedure is in, you need to prefix it with schema name.

   PROCEDURE some_sp
   AS
   BEGIN
      other_schema.some_other_sp('parm1', 10, 20.42);
   END;

In Web Application Projects, Visual Studio needs additional .designer files for pages and user controls. Web Site Projects do not require this overhead. The markup itself is interpreted as the design.

In Java SE environment, by specification you have to specify all classes as you have done:

A list of all named managed persistence classes must be specified in Java SE environments to insure portability

and

If it is not intended that the annotated persistence classes contained in the root of the persistence unit be included in the persistence unit, the exclude-unlisted-classes element should be used. The exclude-unlisted-classes element is not intended for use in Java SE environments.

(JSR-000220 6.2.1.6)

In Java EE environments, you do not have to do this as the provider scans for annotations for you.

Unofficially, you can try to set <exclude-unlisted-classes>false</exclude-unlisted-classes> in your persistence.xml. This parameter defaults to false in EE and truein SE. Both EclipseLink and Toplink supports this as far I can tell. But you should not rely on it working in SE, according to spec, as stated above.

You can TRY the following (may or may not work in SE-environments):

<persistence-unit name="eventractor" transaction-type="RESOURCE_LOCAL">
     <exclude-unlisted-classes>false</exclude-unlisted-classes>

    <properties>
            <property name="hibernate.hbm2ddl.auto" value="validate" />
            <property name="hibernate.show_sql" value="true" />
    </properties>
</persistence-unit>

If you want the dot or other characters with a special meaning in regexes to be a normal character, you have to escape it with a backslash. Since regexes in Java are normal Java strings, you need to escape the backslash itself, so you need two backslashes e.g. \\.

As to me, i need to caffe to my python path. I can add it's path to the file /home/xy/.bashrc by add

export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH.

to my /home/xy/.bashrc file.

But when I use pycharm, the path is still not in.

So I can add path to PYTHONPATH variable, by run -> edit Configuration.

The problem with your code snippet is the way variables are expanded. Variable expansion is usually done when a statement is first read. In your case the whole FOR loop and its block is read and all variables, except the loop variables are expanded to their current value.

This means %c% in your echo %%i, %c% expanded instantly and so is actually used as echo %%i, 1 in each loop iteration.

So what you need is the delayed variable expansion. Find some good explanation about it here.

Variables that should be delay expanded are referenced with !VARIABLE! instead of %VARIABLE%. But you need to activate this feature with setlocal ENABLEDELAYEDEXPANSION and reset it with a matching endlocal.

Your modified code would look something like that:

set TEXT_T="myfile.txt"

set /a c=1

setlocal ENABLEDELAYEDEXPANSION

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
  set /a c=c+1

  echo %%i, !c!
)

endlocal

Add a line getchar(); or system("pause"); before your return 0; in main function. It will work for you.

I found this question looking for a way to do the same thing for my Javascript tests, using Protractor (a javascript frontend to Selenium.)

My solution with protractor 1.2.0 and webdriver 2.1:

browser.actions()
.mouseMove(
  element(by.css('.material-dialog-container'))
)
.click()
.perform();

This also accepts an offset (i'm using it to click above and left of an element:)

browser.actions()
.mouseMove(
  element(by.css('.material-dialog-container'))
  , -20, -20  // pixel offset from top left
)
.click()
.perform();

Run it through a fairly simple regex: [^a-zA-Z]

And then check it's length separately:

if(string.Length > 7)

ax.axis('off'), will as Joe Kington pointed out, remove everything except the plotted line.

For those wanting to only remove the frame (border), and keep labels, tickers etc, one can do that by accessing the spines object on the axis. Given an axis object ax, the following should remove borders on all four sides:

ax.spines['top'].set_visible(False)
ax.spines['right'].set_visible(False)
ax.spines['bottom'].set_visible(False)
ax.spines['left'].set_visible(False)

And, in case of removing x and y ticks from the plot:

 ax.get_xaxis().set_ticks([])
 ax.get_yaxis().set_ticks([])

I use something like this (you should add code to deal with the various fails):

    var response = RunTaskWithTimeout<ReturnType>(
        (Func<ReturnType>)delegate { return SomeMethod(someInput); }, 30);


    /// <summary>
    /// Generic method to run a task on a background thread with a specific timeout, if the task fails,
    /// notifies a user
    /// </summary>
    /// <typeparam name="T">Return type of function</typeparam>
    /// <param name="TaskAction">Function delegate for task to perform</param>
    /// <param name="TimeoutSeconds">Time to allow before task times out</param>
    /// <returns></returns>
    private T RunTaskWithTimeout<T>(Func<T> TaskAction, int TimeoutSeconds)
    {
        Task<T> backgroundTask;

        try
        {
            backgroundTask = Task.Factory.StartNew(TaskAction);
            backgroundTask.Wait(new TimeSpan(0, 0, TimeoutSeconds));
        }
        catch (AggregateException ex)
        {
            // task failed
            var failMessage = ex.Flatten().InnerException.Message);
            return default(T);
        }
        catch (Exception ex)
        {
            // task failed
            var failMessage = ex.Message;
            return default(T);
        }

        if (!backgroundTask.IsCompleted)
        {
            // task timed out
            return default(T);
        }

        // task succeeded
        return backgroundTask.Result;
    }

<form name="myForm" method="post">
  <p>Activity</p>

In Node.js, you can set global variables via the "global" or "GLOBAL" object:

GLOBAL._ = require('underscore'); // But you "shouldn't" do this! (see note below)

or more usefully...

GLOBAL.window = GLOBAL;  // Like in the browser

From the Node.js source, you can see that these are aliased to each other:

node-v0.6.6/src/node.js:
28:     global = this;
128:    global.GLOBAL = global;

In the code above, "this" is the global context. With the CommonJS module system (which Node.js uses), the "this" object inside of a module (i.e., "your code") is not the global context. For proof of this, see below where I spew the "this" object and then the giant "GLOBAL" object.

console.log("\nTHIS:");
console.log(this);
console.log("\nGLOBAL:");
console.log(global);

/* Outputs ...

** Note: regarding setting "GLOBAL._", in general you should just do var _ = require('underscore');. Yes, you do that in every single file that uses Underscore.js, just like how in Java you do import com.foo.bar;. This makes it easier to figure out what your code is doing because the linkages between files are 'explicit'. It is mildly annoying, but a good thing. .... That's the preaching.

There is an exception to every rule. I have had precisely exactly one instance where I needed to set "GLOBAL._". I was creating a system for defining "configuration" files which were basically JSON, but were "written in JavaScript" to allow a bit more flexibility. Such configuration files had no 'require' statements, but I wanted them to have access to Underscore.js (the entire system was predicated on Underscore.js and Underscore.js templates), so before evaluating the "configuration", I would set "GLOBAL._". So yeah, for every rule, there's an exception somewhere. But you had better have a darn good reason and not just "I get tired of typing 'require', so I want to break with the convention".

Use is_same:

#include <type_traits>

template <typename T>
void foo()
{
    if (std::is_same<T, animal>::value) { /* ... */ }  // optimizable...
}

Usually, that's a totally unworkable design, though, and you really want to specialize:

template <typename T> void foo() { /* generic implementation  */ }

template <> void foo<animal>()   { /* specific for T = animal */ }

Note also that it's unusual to have function templates with explicit (non-deduced) arguments. It's not unheard of, but often there are better approaches.

try using 'acroread' in a simple script like the one above

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

Mcrypt PECL extenstion

 sudo apt-get -y install gcc make autoconf libc-dev pkg-config
 sudo apt-get -y install libmcrypt-dev
 sudo pecl install mcrypt-1.0.1

When you are shown the prompt

 libmcrypt prefix? [autodetect] :

Press [Enter] to autodetect.

After success installing mcrypt trought pecl, you should add mcrypt.so extension to php.ini.

The output will look like this:

...
Build process completed successfully
Installing '/usr/lib/php/20170718/mcrypt.so'    ---->   this is our path to mcrypt extension lib
install ok: channel://pecl.php.net/mcrypt-1.0.1
configuration option "php_ini" is not set to php.ini location
You should add "extension=mcrypt.so" to php.ini

Grab installing path and add to cli and apache2 php.ini configuration.

sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/cli/conf.d/mcrypt.ini"
sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/apache2/conf.d/mcrypt.ini"

Verify that the extension was installed

Run command:

php -i | grep "mcrypt"

The output will look like this:

/etc/php/7.2/cli/conf.d/mcrypt.ini
Registered Stream Filters => zlib.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, convert.iconv.*, mcrypt.*, mdecrypt.*

Using equals() LocalDate does override equals:

int compareTo0(LocalDate otherDate) {
    int cmp = (year - otherDate.year);
    if (cmp == 0) {
        cmp = (month - otherDate.month);
        if (cmp == 0) {
            cmp = (day - otherDate.day);
        }
    }
    return cmp;
}

If you are not happy with the result of equals(), you are good using the predefined methods of LocalDate.

• isAfter()
• isBefore()
• isEqual()

Notice that all of those method are using the compareTo0() method and just check the cmp value. if you are still getting weird result (which you shouldn't), please attach an example of input and output

I have used the answer given by senderle for a long time until I discovered np.argsort. Here is how it works.

# idx works on np.array and not lists.
list1 = np.array([3,2,4,1])
list2 = np.array(["three","two","four","one"])
idx   = np.argsort(list1)

list1 = np.array(list1)[idx]
list2 = np.array(list2)[idx]

I find this solution more intuitive, and it works really well. The perfomance:

def sorting(l1, l2):
    # l1 and l2 has to be numpy arrays
    idx = np.argsort(l1)
    return l1[idx], l2[idx]

# list1 and list2 are np.arrays here...
%timeit sorting(list1, list2)
100000 loops, best of 3: 3.53 us per loop

# This works best when the lists are NOT np.array
%timeit zip(*sorted(zip(list1, list2)))
100000 loops, best of 3: 2.41 us per loop

# 0.01us better for np.array (I think this is negligible)
%timeit tups = zip(list1, list2); tups.sort(); zip(*tups)
100000 loops, best for 3 loops: 1.96 us per loop

Even though np.argsort isn't the fastest one, I find it easier to use.

Here's a variant that uses fancy indexing and has the actual values as an intermediate:

p31 = numpy.asarray(o31)
values = p31[p31<200]
za = len(values)

Edit:

Use a transform stream.

With a BufferedReader you can read lines.

new BufferedReader ("lorem ipsum", { encoding: "utf8" })
    .on ("error", function (error){
        console.log ("error: " + error);
    })
    .on ("line", function (line){
        console.log ("line: " + line);
    })
    .on ("end", function (){
        console.log ("EOF");
    })
    .read ();

Logout from HTTP Basic Auth in two steps

Let’s say I have a HTTP Basic Auth realm named “Password protected”, and Bob is logged in. To log out I make 2 AJAX requests:

1. Access script /logout_step1. It adds a random temporary user to .htusers and responds with its login and password.
2. Access script /logout_step2 authenticated with the temporary user’s login and password. The script deletes the temporary user and adds this header on the response: WWW-Authenticate: Basic realm="Password protected"

At this point browser forgot Bob’s credentials.

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

Was able to find the solution. Since the date I am getting is in ISO format, only providing date to moment will validate it, no need to pass the dateFormat.

var date = moment("2016-10-19");

And then date.isValid() gives desired result.

Yes, the error you are getting means that there is not a private key on your Mac associated with the distribution certificate you are trying to use to sign the app.

There are two possible solutions, depending on whether the computer who requested the distribution certificate is available or not.

If the computer who requested the distribution certificate is available (or there is a backup of the distribution assets somewhere)

1. From the computer where the distribution asset was generated, open Xcode.
2. Click on Window, Organizer.
3. Expand the Teams section.
4. Select your team, select the certificate of "iOS Distribution" type, click Export and follow the instructions.
5. Save the exported file and go to your computer.
6. Repeat steps 1-3.
7. Click Import and select the file you exported before.

If the computer where the distribution profile was created is not accessible anymore (and there is not a backup)

You have to revoke the certificate and create a new one.

You may need to ask your team admin or agent to give you some privileges in order to generate distribution certificates. Once you have enough privileges, follow these steps (accurate as of 15-May-2013):

1. Go to this webpage: https://developer.apple.com/devcenter/ios/index.action
2. Click on "Member Center" and enter your iOS developer credentials.
3. Click on "Certificates, Identifiers & Profiles".
4. Click on "Certificates" under the "iOS Apps" section.
5. Expand the Certificates section on the left, select Distribution, and click on your distribution certificate.
6. Click Revoke and follow the instructions.
7. Click on the plus sign to add a new certificate.
8. Select "App Store and Ad Hoc" option, and click Continue.
9. Follow the steps printed in the webpage. That involves opening the Keychain application on your Mac and generate a Certificate Signing Request from there. Click Continue.
10. Upload the .csr file and click Continue.
11. A certificate is generated for distribution. Download it and double click it to integrate it in your keychain.

Reopen Xcode and check your project configuration to see if you can now select an "iPhone Distribution" certificate (i.e. it's not grayed out).

If you need to change a file just once. You should prefer making the change locally and build a new docker image with this file.

Say in a docker image, you need to change a file named myFile.xml under /path/to/docker/image/. So, you need to do.

1. Copy myFile.xml in your local filesystem and make necessary changes.
2. Create a file named 'Dockerfile' with the following content-

FROM docker-repo:tag
ADD myFile.xml /path/to/docker/image/

Then build your own docker image with docker build -t docker-repo:v-x.x.x .

Then use your newly build docker image.

Use this as an example:

docker create --name new_ubuntu -it -p 8080:8080 -p  15672:15672 -p 5432:5432   ubuntu:latest bash

look what you've created(and copy its CONTAINER ID xxxxx):

docker ps -a 

now write the miracle maker word(start):

docker start xxxxx

good luck

All I had to do was to install this

npm install @angular/animations@latest --save  

and then import

import { BrowserAnimationsModule } from '@angular/platform-browser/animations'; 

into your app.module.ts file.

The syntax to statically initialize an array uses curly braces, like this:

int array[10] = { 0 };

This will zero-initialize the array.

For multi-dimensional arrays, you need nested curly braces, like this:

int cipher[Array_size][Array_size]= { { 0 } };

Note that Array_size must be a compile-time constant for this to work. If Array_size is not known at compile-time, you must use dynamic initialization. (Preferably, an std::vector).

If you are looking for a direct approach and using a local File in that case. Try

<div
style={{ background-image: 'url(' + Image + ')', background-size: 'auto' }}
/>

This is the case of JS with inline styling where Image is a local file that you must have imported with a path.

Most of previous examples will raise an exception in case your string is not long enough.

Another approach is to use 'yourstring'.ljust(100)[:100].strip().

This will give you first 100 chars. You might get a shorter string in case your string last chars are spaces.

I've had a similar issue, and I've resolved it by statically linking libstdc++ into the program I was compiling, like so:

$ LIBS=-lstdc++ ./configure ... etc.

instead of the usual

$ ./configure ... etc.

There might be problems with this solution to do with loading shared libraries at runtime, but I haven't looked into the issue deeply enough to comment.

There is an elegant way in the Airbnb Style Guide to do this (ECMAScript 7):

const myObject = {
  a: 1,
  b: 2,
  c: 3
};
const { a, ...noA } = myObject;
console.log(noA); // => { b: 2, c: 3 }

If you have a very limited number of levels, you could try converting y into factor and change its levels.

> xy <- data.frame(x = c(1, 2, 4), y = c(1, 4, 5))
> xy$w <- as.factor(xy$y)
> levels(xy$w) <- c("good", "fair", "bad")
> xy
  x y    w
1 1 1 good
2 2 4 fair
3 4 5  bad

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before and an :after pseudo-element — it just cannot have more than one of each kind.)

As a result, when you have multiple :before rules matching the same element, they will all cascade and apply to a single :before pseudo-element, as with a normal element. In your example, the end result looks like this:

.circle.now:before {
    content: "Now";
    font-size: 19px;
    color: black;
}

As you can see, only the content declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.

This behavior is described in the Selectors section of CSS2.1:

Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.

This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.

If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before or .now.circle:before — whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content property that you will need to define yourself.

If you still need a concrete example, see my answer to this similar question.

The legacy css3-content specification contains a section on inserting multiple ::before and ::after pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.

Per the documentation you posted, and this blog post - there's no difference when declaring the primitive between an unsigned int/long and a signed one. The "new support" is the addition of the static methods in the Integer and Long classes, e.g. Integer.divideUnsigned. If you're not using those methods, your "unsigned" long above 2^63-1 is just a plain old long with a negative value.

From a quick skim, it doesn't look like there's a way to declare integer constants in the range outside of +/- 2^31-1, or +/- 2^63-1 for longs. You would have to manually compute the negative value corresponding to your out-of-range positive value.

Windows environment, local machine. I had an error

[js] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: 
Error connecting to 127.0.0.1:27017 :: caused by :: 
No connection could be made because the target machine actively refused it. :

After some back and forth attempts I decided

• to check Windows "Task Manager". I noticed that MongoDB process is stopped.
• I made it run. Everything starts working as expected.

Or in C# 3.0 using System.Linq you can skip the intermediate list:

private Update BuildMetaData(MetaData[] nvPairs)
{
        Update update = new Update();
        var ip = from nv in nvPairs
                 select new InputProperty()
                 {
                     Name = "udf:" + nv.Name,
                     Val = nv.Value
                 };
        update.Items = ip.ToArray();
        return update;
}

Well, found a solution to my problem; Updating all rows using a SQL query and a SQL Task in SSIS Like Below. May help others if they face same challenge in future.

update Original 
set Original.Vaal= t.vaal 
from Original join (select * from staging1  union   select * from staging2) t 
on Original.id=t.id

instead of click on Restore Database click on Restore File and Filegroups..

thats work on my sql server

This could happen if you are using reflection to GetProperty of an object which is null.

Another tip: I initialized static fields in a wrong order - surprisingly it didn't bring up a Problem (NullPointerException?), instead Eclipse complained with exactly the message OP posted. Correcting the static initialization order made the class run-able. Example:

private static ScriptEngineManager factory = null;
private static ScriptEngine engine = null;
static {
    engine = factory.getEngineByName("JavaScript");
    // factory is supposed to initialize FIRST
    factory = new ScriptEngineManager();
}

GetDistance is the best solution, but in many cases we can't use this Method (e.g. Universal App)

• Pseudocode of the Algorithm to calculate the distance between to coorindates:

  public static double DistanceTo(double lat1, double lon1, double lat2, double lon2, char unit = 'K')
  {
      double rlat1 = Math.PI*lat1/180;
      double rlat2 = Math.PI*lat2/180;
      double theta = lon1 - lon2;
      double rtheta = Math.PI*theta/180;
      double dist =
          Math.Sin(rlat1)*Math.Sin(rlat2) + Math.Cos(rlat1)*
          Math.Cos(rlat2)*Math.Cos(rtheta);
      dist = Math.Acos(dist);
      dist = dist*180/Math.PI;
      dist = dist*60*1.1515;
  
      switch (unit)
      {
          case 'K': //Kilometers -> default
              return dist*1.609344;
          case 'N': //Nautical Miles 
              return dist*0.8684;

Modify registry for IE:

1. HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main
2. Right-click ? New ? String Value ? Value name: TabProcGrowth (create if not exist)
3. TabProcGrowth (right-click) ? Modify... ? Value data: 0

Source: Selenium WebDriver windows switching issue in Internet Explorer 8-10

For my case, IE began detecting new window handles after the registry edit.

Taken from the MSDN Blog:

Tab Process Growth : Sets the rate at which IE creates New Tab processes.

The "Max-Number" algorithm: This specifies the maximum number of tab processes that may be executed for a single isolation session for a single frame process at a specific mandatory integrity level (MIC). Relative values are:

• TabProcGrowth=0 : tabs and frames run within the same process; frames are not unified across MIC levels.
• TabProcGrowth =1: all tabs for a given frame process run in a single tab process for a given MIC level.

WebDriver: IEDriverServer x64 3.5.1

public static String openWindow(WebDriver driver, By by) throws IOException {
String parentHandle = driver.getWindowHandle(); // Save parent window
WebElement clickableElement = driver.findElement(by);
clickableElement.click(); // Open child window
WebDriverWait wait = new WebDriverWait(driver, 10); // Timeout in 10s

        if (!parentHandle.equals(handle)) {
            break;
        }
    }
    driver.manage().window().maximize();

return parentHandle; // Returns parent window if need to switch back
}



/* How to use method */
String parentHandle = Selenium.openWindow(driver, by);

// Do things in child window
driver.close();

// Return to parent window
driver.switchTo().window(parentHandle);

The above code includes an if-check to make sure you are not switching to the parent window as Set<T> has no guaranteed ordering in Java. WebDriverWait appears to increase the chance of success as supported by below statement.

Quoted from Luke Inman-Semerau: (Developer for Selenium)

The browser may take time to acknowledge the new window, and you may be falling into your switchTo() loop before the popup window appears.

You automatically assume that the last window returned by getWindowHandles() will be the last one opened. That's not necessarily true, as they are not guaranteed to be returned in any order.

Use decimal. It doesn't have this "problem".

This will also work great, u can do something else while a new tab handler the submit .

<form target="_blank">
    <a href="#">Submit</a>
</form>

<script>
    $('a').click(function () {
        // do something you want ...

        $('form').submit();
    });
</script>

By the way guys, (int)Decimal.MaxValue will overflow. You can't get the "int" part of a decimal because the decimal is too friggen big to put in the int box. Just checked... its even too big for a long (Int64).

If you want the bit of a Decimal value to the LEFT of the dot, you need to do this:

Math.Truncate(number)

and return the value as... A DECIMAL or a DOUBLE.

edit: Truncate is definitely the correct function!

I use the following to keep all the temporary and backup files in one place:

set backup
set backupdir=~/.vim/backup
set directory=~/.vim/tmp

Saves cluttering working directories all over the place.

You will have to create these directories first, vim will not create them for you.

I use the little utility which comes with PureMPI.net called execcmd.exe. Its syntax is as follows:

execcmd \\yourremoteserver <your command here>

Doesn't get any simpler than this :)

Most simple way (assumed you want to remove the element)

<span id='close' onclick='this.parentNode.parentNode.parentNode.removeChild(this.parentNode.parentNode); return false;'>x</span>

Add this inside your div, an example here.

You may also use something like this

window.onload = function(){
    document.getElementById('close').onclick = function(){
        this.parentNode.parentNode.parentNode
        .removeChild(this.parentNode.parentNode);
        return false;
    };
};

An Example Here.

Css for close button

#close {
    float:right;
    display:inline-block;
    padding:2px 5px;
    background:#ccc;
}

You may add a hover effect like

#close:hover {
    float:right;
    display:inline-block;
    padding:2px 5px;
    background:#ccc;
    color:#fff;
}

Something like this one.

Easy way, use type="number" if it works for your use case:

<input type="number" ng-model="myText" name="inputName">

Another easy way: ng-pattern can also be used to define a regex that will limit what is allowed in the field. See also the "cookbook" page about forms.

Hackish? way, $watch the ng-model in your controller:

<input type="text"  ng-model="myText" name="inputName">

Controller:

$scope.$watch('myText', function() {
   // put numbersOnly() logic here, e.g.:
   if ($scope.myText  ... regex to look for ... ) {
      // strip out the non-numbers
   }
})

Best way, use a $parser in a directive. I'm not going to repeat the already good answer provided by @pkozlowski.opensource, so here's the link: https://stackoverflow.com/a/14425022/215945

All of the above solutions involve using ng-model, which make finding this unnecessary.

Using ng-change will cause problems. See AngularJS - reset of $scope.value doesn't change value in template (random behavior)

This works:

<div>
    <input type="text" 
        style="margin: 5px; padding: 4px; border: 1px solid; 
        width: 200px; width: calc(100% - 20px);">
</div>

The first 'width' is a fallback rule for older browsers.

System.out.println() also outputs to LogCat. The benefit of using good old System.out.println() is that you can print an object like System.out.println(object) to the console if you need to check if a variable is initialized or not.

Log.d, Log.v, Log.w etc methods only allow you to print strings to the console and not objects. To circumvent this (if you desire), you must use String.format.

It's a design pattern and it's not specific to c#. More about it all over the internet and SO, like on this wikipedia article.

In software engineering, the singleton pattern is a design pattern that is used to restrict instantiation of a class to one object. This is useful when exactly one object is needed to coordinate actions across the system. The concept is sometimes generalized to systems that operate more efficiently when only one object exists, or that restrict the instantiation to a certain number of objects (say, five). Some consider it an anti-pattern, judging that it is overused, introduces unnecessary limitations in situations where a sole instance of a class is not actually required, and introduces global state into an application.

You should use it if you want a class that can only be instanciated once.

NullSafe Operator "?->" (possibly) since php8

In PHP8 it's been accepted this new operator, you can find the documentation here. ?-> it's the NullSafe Operator, it returns null in case you try to invoke functions or get values from null...

Examples:

<?php
$obj = null;
$obj = $obj?->attr; //return null
$obj = ?->funct(); // return null
$obj = $objDrive->attr; // Error: Trying to get property 'attr' of non-object
?>

select View-->DBMS Output in menu and

You don't have any example code but I assume you want to do something like this?

@View({
directives: [NgClass],
styles: [`
    .${TodoModel.COMPLETED}  {
        text-decoration: line-through;
    }
    .${TodoModel.STARTED} {
        color: green;
    }
`],
template: `<div>
                <span [ng-class]="todo.status" >{{todo.title}}</span>
                <button (click)="todo.toggle()" >Toggle status</button>
            </div>`
})

You assign ng-class to a variable which is dynamic (a property of a model called TodoModel as you can guess).

todo.toggle() is changing the value of todo.status and there for the class of the input is changing.

This is an example for class name but actually you could do the same think for css properties.

I hope this is what you meant.

This example is taken for the great egghead tutorial here.

To cast, the actual object must be of a Type equal to or derived from the Type you are attempting to cast to...

or, to state it in the opposite way, the Type you are trying to cast it to must be the same as, or a base class of, the actual type of the object.

if your actual object is of type Baseclass, then you can't cast it to a derived class Type...

command-line-args is worth a look!

You can set options using the main notation standards (learn more). These commands are all equivalent, setting the same values:

$ example --verbose --timeout=1000 --src one.js --src two.js
$ example --verbose --timeout 1000 --src one.js two.js
$ example -vt 1000 --src one.js two.js
$ example -vt 1000 one.js two.js

To access the values, first create a list of option definitions describing the options your application accepts. The type property is a setter function (the value supplied is passed through this), giving you full control over the value received.

const optionDefinitions = [
  { name: 'verbose', alias: 'v', type: Boolean },
  { name: 'src', type: String, multiple: true, defaultOption: true },
  { name: 'timeout', alias: 't', type: Number }
]

Next, parse the options using commandLineArgs():

const commandLineArgs = require('command-line-args')
const options = commandLineArgs(optionDefinitions)

options now looks like this:

{
  src: [
    'one.js',
    'two.js'
  ],
  verbose: true,
  timeout: 1000
}

Advanced usage

Beside the above typical usage, you can configure command-line-args to accept more advanced syntax forms.

Command-based syntax (git style) in the form:

$ executable <command> [options]

For example.

$ git commit --squash -m "This is my commit message"

Command and sub-command syntax (docker style) in the form:

$ executable <command> [options] <sub-command> [options]

For example.

$ docker run --detached --image centos bash -c yum install -y httpd

Usage guide generation

A usage guide (typically printed when --help is set) can be generated using command-line-usage. See the examples below and read the documentation for instructions how to create them.

A typical usage guide example.

The polymer-cli usage guide is a good real-life example.

There is plenty more to learn, please see the wiki for examples and documentation.

Immutable insertion

Using splice method is surely the best answer if you need to insert into an array in-place.

However, if you are looking for an immutable function that returns a new updated array instead of mutating the original array on insert, you can use the following function.

function insert(array, index) {
  const items = Array.prototype.slice.call(arguments, 2);

  return [].concat(array.slice(0, index), items, array.slice(index));
}

const list = ['one', 'two', 'three'];

const list1 = insert(list, 0, 'zero'); // Insert single item
const list2 = insert(list, 3, 'four', 'five', 'six'); // Insert multiple


console.log('Original list: ', list);
console.log('Inserted list1: ', list1);
console.log('Inserted list2: ', list2);

Note: This is a pre-ES2015 way of doing it so it works for both older and newer browsers.

If you're using ES6 then you can try out rest parameters too; see this answer.

Assuming you have an ArrayList that contains characters, you could do this:

List<Character> list = new ArrayList<Character>();
list.addAll(Arrays.asList('+', '-', '*', '^'));

Anhil's answer helped me a lot.

However, after experimenting further I noticed that the solution suggested sometimes causes a not-so-pretty UI glitch.

Instead, going for this approach* did the trick for me.

*Swift 2.1

//Create an instance of a UITableViewController. This will host your UITableView.
private let tableViewController = UITableViewController()

//Add tableViewController as a childViewController and set its tableView property to your UITableView.
self.addChildViewController(self.tableViewController)
self.tableViewController.tableView = self.tableView
self.refreshControl.addTarget(self, action: "refreshData:", forControlEvents: .ValueChanged)
self.tableViewController.refreshControl = self.refreshControl

While the marked answer gets it working, all you really need to add to the webconfig is:

    <handlers>
      <!-- Your other remove tags-->
      <remove name="UrlRoutingModule-4.0"/>
      <!-- Your other add tags-->
      <add name="UrlRoutingModule-4.0" path="*" verb="*" type="System.Web.Routing.UrlRoutingModule" preCondition=""/>
    </handlers>

Note that none of those have a particular order, though you want your removes before your adds.

The reason that we end up getting a 404 is because the Url Routing Module only kicks in for the root of the website in IIS. By adding the module to this application's config, we're having the module to run under this application's path (your subdirectory path), and the routing module kicks in.

Yet another option is to use the decimal module:

import numpy as np
from decimal import *

arr = np.array([  56.83,  385.3 ,    6.65,  126.63,   85.76,  192.72,  112.81, 10.55])
arr2 = [str(Decimal(i).quantize(Decimal('.01'))) for i in arr]

# ['56.83', '385.30', '6.65', '126.63', '85.76', '192.72', '112.81', '10.55']

You can find what is the php.ini file used:

• By add phpinfo() in a php page and display the page (like the picture under)
• From the shell, enter: php -i

Next, you can find the information in the Loaded Configuration file (so here it's /user/local/etc/php/php.ini)

Sometimes, you have indicated (none), in this case you just have to put your custom php.ini that you can find here: http://git.php.net/?p=php-src.git;a=blob;f=php.ini-production;hb=HEAD

I hope this answer will help.

Works fine for me

See example here. http://jsfiddle.net/blowsie/c6VAy/

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>

Update,

A working example of your full code (pretty much) here. http://jsfiddle.net/blowsie/c6VAy/3/

You can also use System.lineSeparator():

String x = "Hello," + System.lineSeparator() + "there";

I came here from google so it might be relevant to others: for yarn you could use:

yarn --cwd /path/to/your/app run start 

The other answers have one problem: they rely on the action you do and not on the link itself to decide whether to load it in Safari or in webview.

Now sometimes this is exactly what you want, which is fine; but some other times, especially if you have anchor links in your page, you want really to open only external links in Safari, and not internal ones. In that case you should check the URL.host property of your request.

I use that piece of code to check whether I have a hostname in the URL that is being parsed, or if it is embedded html:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    static NSString *regexp = @"^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9-]*[a-zA-Z0-9])[.])+([A-Za-z]|[A-Za-z][A-Za-z0-9-]*[A-Za-z0-9])$";
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regexp];

    if ([predicate evaluateWithObject:request.URL.host]) {
        [[UIApplication sharedApplication] openURL:request.URL];
        return NO; 
    } else {
        return YES; 
    }
}

You can of course adapt the regular expression to fit your needs.

You can download and run the setup file. This should install your AWK in "C:\Program Files (x86)\GnuWin32". You can run the awk or gawk command from the bin folder or add the folder ``C:\Program Files (x86)\GnuWin32\binto yourPATH`.

More general sorted, where the key keyword defines the sorting method, minus before numerical type indicates descending:

>>> x = Counter({'a':5, 'b':3, 'c':7})
>>> sorted(x.items(), key=lambda k: -k[1])  # Ascending
[('c', 7), ('a', 5), ('b', 3)]

Use this code in your php script (first lines)

ini_set('allow_url_fopen',1);

This is a faster/simpler (and prototypical) variation of the function that Josh posted:

String.prototype.format = String.prototype.f = function() {
    var s = this,
        i = arguments.length;

    while (i--) {
        s = s.replace(new RegExp('\\{' + i + '\\}', 'gm'), arguments[i]);
    }
    return s;
};

Usage:

'Added {0} by {1} to your collection'.f(title, artist)
'Your balance is {0} USD'.f(77.7) 

I use this so much that I aliased it to just f, but you can also use the more verbose format. e.g. 'Hello {0}!'.format(name)

the module.exports property or the exports object allows a module to select what should be shared with the application

I have a video on module_export available here

Using domain Name may solve the problem (get domain name using powershell: $env:userdomain):

    Hashtable<String, Object> env = new Hashtable<String, Object>();
    String principalName = "domainName\\userName";
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://URL:389/OU=ou-xx,DC=fr,DC=XXXXXX,DC=com");
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, principalName);
    env.put(Context.SECURITY_CREDENTIALS, "Your Password");

    try {
        DirContext authContext = new InitialDirContext(env);
        // user is authenticated
        System.out.println("USER IS AUTHETICATED");
    } catch (AuthenticationException ex) {
        // Authentication failed
        System.out.println("AUTH FAILED : " + ex);

    } catch (NamingException ex) {
        ex.printStackTrace();
    }

You can use

import heapq
listForTree = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]    
heapq.heapify(listForTree)             # for a min heap
heapq._heapify_max(listForTree)        # for a maxheap!!

If you then want to pop elements, use:

heapq.heappop(minheap)      # pop from minheap
heapq._heappop_max(maxheap) # pop from maxheap

Android OFFICIALLY supports Java 8 as of Android N.

Feature announcements are here, the Java 8 language announcement is:

Improved Java 8 language support - We’re excited to bring Java 8 language features to Android. With Android's Jack compiler, you can now use many popular Java 8 language features, including lambdas and more, on Android versions as far back as Gingerbread. The new features help reduce boilerplate code. For example, lambdas can replace anonymous inner classes when providing event listeners. Some Java 8 language features --like default and static methods, streams, and functional interfaces -- are also now available on N and above. With Jack, we’re looking forward to tracking the Java language more closely while maintaining backward compatibility.

this gives you the Xact;

System.Data.SqlClient.SqlConnectionStringBuilder connBuilder = new System.Data.SqlClient.SqlConnectionStringBuilder();

connBuilder.ConnectionString = connectionString;

string server = connBuilder.DataSource;           //-> this gives you the Server name.
string database = connBuilder.InitialCatalog;     //-> this gives you the Db name.

If you have luasocket installed:

local socket = require 'socket'
socket.sleep(0.2)

This linker error message suggests that the source file defining it is not marked as being part of your app target. Find that source file, and use the File property inspector on the right to check the target membership entry for your app target.

Solution: Select the file -> openFile Inspector -> see Target Membership -> check if unchecked target your running target

Your second solution is probably the most correct. You should use the HTTP spec and mimetypes the way they were intended and upload the file via multipart/form-data. As far as handling the relationships, I'd use this process (keeping in mind I know zero about your assumptions or system design):

1. POST to /users to create the user entity.
2. POST the image to /images, making sure to return a Location header to where the image can be retrieved per the HTTP spec.
3. PATCH to /users/carPhoto and assign it the ID of the photo given in the Location header of step 2.

I noticed some time ago that a For loop typically generates several more machine instructions than a while loop. However, if you look closely at the examples, which mirror my observations, the difference is two or three machine instructions, hardly worth much consideration.

Note, too, that the initializer for a WHILE loop can be eliminated by baking it into the code, e. g.:

static int intStartWith = 100;

The static modifier bakes the initial value into the code, saving (drum roll) one MOV instruction. Of greater significance, marking a variable as static moves it outside the stack frame. Variable alignment permitting, it may also produce slightly smaller code, too, since the MOV instruction and its operands take more room than, for example an integer, Boolean, or character value (either ANSI or Unicode).

However, if variables are aligned on 8 byte boundaries, a common default setting, an int, bool, or TCHAR baked into code costs the same number of bytes as a MOV instruction.

Try this:

a = 1
b = 2
int_div  = a // b

Erik Aigner,

Please use $dirty(The field has been modified) and $invalid (The field content is not valid).

Please check below examples for angular form validation

1)

Validation example HTML for user enter inputs:

<form  ng-app="myApp"  ng-controller="validateCtrl" name="myForm" novalidate>
  <p>Email:<br>
    <input type="email" name="email" ng-model="email" required>
    <span ng-show="myForm.email.$dirty && myForm.email.$invalid">
      <span ng-show="myForm.email.$error.required">Email is required.</span>
      <span ng-show="myForm.email.$error.email">Invalid email address.</span>
      </span>
  </p>
    </form>

2)

Validation example HTML/Js for user submits :

      <form  ng-app="myApp"  ng-controller="validateCtrl" name="myForm" novalidate form-submit-validation="">
      <p>Email:<br>
        <input type="email" name="email" ng-model="email" required>
        <span ng-show="submitted || myForm.email.$dirty && myForm.email.$invalid">
          <span ng-show="myForm.email.$error.required">Email is required.</span>
          <span ng-show="myForm.email.$error.email">Invalid email address.</span>
          </span>
      </p>
<p>
  <input type="submit">
</p>
</form>

Custom Directive :

app.directive('formSubmitValidation', function () {

        return {
            require: 'form',
            compile: function (tElem, tAttr) {

                tElem.data('augmented', true);

                return function (scope, elem, attr, form) {
                    elem.on('submit', function ($event) {
                        scope.$broadcast('form:submit', form);

                        if (!form.$valid) {
                            $event.preventDefault();
                        }
                        scope.$apply(function () {
                            scope.submitted = true;
                        });


                    });
                }
            }
        };


  })

3)

you don't want use directive use ng-change function like below

  <form  ng-app="myApp"  ng-controller="validateCtrl" name="myForm" novalidate ng-change="submitFun()">
      <p>Email:<br>
        <input type="email" name="email" ng-model="email" required>
        <span ng-show="submitted || myForm.email.$dirty && myForm.email.$invalid">
          <span ng-show="myForm.email.$error.required">Email is required.</span>
          <span ng-show="myForm.email.$error.email">Invalid email address.</span>
          </span>
      </p>
<p>
  <input type="submit">
</p>
</form>

Controller SubmitFun() JS:

 var app = angular.module('example', []);
 app.controller('exampleCntl', function($scope) {
 $scope.submitFun = function($event) {
 $scope.submitted = true;
  if (!$scope.myForm.$valid) 
  {
        $event.preventDefault();
   }
  }

});

Because abstract classes have state (fields) and somethimes they need to be initialized somehow.

Change the return type of your GetResults to be List<Person>.
Eliminate the code that you use to serialize the List to a json string - WCF does this for you automatically.

Using your definition for the Person class, this code works for me:

public List<Person> GetPlayers()
{
    List<Person> players = new List<Person>();
    players.Add(new  Person { FirstName="Peyton", LastName="Manning", Age=35 } );
    players.Add(new  Person { FirstName="Drew", LastName="Brees", Age=31 } );
    players.Add(new  Person { FirstName="Brett", LastName="Favre", Age=58 } );

    return players;
}

results:

[{"Age":35,"FirstName":"Peyton","LastName":"Manning"},  
 {"Age":31,"FirstName":"Drew","LastName":"Brees"},  
 {"Age":58,"FirstName":"Brett","LastName":"Favre"}]

(All on one line)

I also used this attribute on the method:

[WebInvoke(Method = "GET",
           RequestFormat = WebMessageFormat.Json,
           ResponseFormat = WebMessageFormat.Json,
           UriTemplate = "players")]

WebInvoke with Method= "GET" is the same as WebGet, but since some of my methods are POST, I use all WebInvoke for consistency.

The UriTemplate sets the URL at which the method is available. So I can do a GET on http://myserver/myvdir/JsonService.svc/players and it just works.

Also check out IIRF or another URL rewriter to get rid of the .svc in the URI.

If you need only an integer representing elapsed days since Jan. 1, 1970, you can try these:

// magic number=
// millisec * sec * min * hours
// 1000 * 60 * 60 * 24 = 86400000
public static final long MAGIC=86400000L;

public int DateToDays (Date date){
    //  convert a date to an integer and back again
    long currentTime=date.getTime();
    currentTime=currentTime/MAGIC;
    return (int) currentTime; 
}

public Date DaysToDate(int days) {
    //  convert integer back again to a date
    long currentTime=(long) days*MAGIC;
    return new Date(currentTime);
}

Shorter but less readable (slightly faster?):

public static final long MAGIC=86400000L;

public int DateToDays (Date date){
    return (int) (date.getTime()/MAGIC);
}

public Date DaysToDate(int days) {
    return new Date((long) days*MAGIC);
}

Hope this helps.

EDIT: This could work until Fri Jul 11 01:00:00 CET 5881580

There are very good examples here to start trying with, but all of them are based on adding some extra or external element like a "div" as a reference element to drag it, and calculate the new dimensions or position of the original element.

Here's an example that doesn't use any extra elements. We could add borders, padding or margin without affecting its operation. In this example we have not added color, nor any visual reference to the borders nor to the lower right corner as a clue where you can enlarge or reduce dimensions, but using the cursor around the resizable elements the clues appears!

let resizerForCenter = new Resizer('center')  
resizerForCenter.initResizer()

Don't worry about it. In your code, just do the separate / and % operations as you mention, even though it might seem like it's inefficient. Let the JIT compiler worry about combining these operations to get both quotient and remainder in a single machine instruction (as far as I recall, it generally does).

you can swipe the key and the value. For example

        String[] k = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil"};
        int[] v = {341, 273, 278, 329, 445};
        TreeMap<Integer,String>a=new TreeMap();
        for (int i = 0; i < k.length; i++) 
           a.put(v[i],k[i]);            
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
        a.remove(a.firstEntry().getKey());
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());

You probably need to do a git stash before you git pull, this is because it is reading your old config file. So do:

git stash
git pull
git commit -am <"say first commit">
git push

Also see git-stash(1) Manual Page.

if you are allowed to do it globally then you can set the session time out in

TOMCAT_HOME/conf/web.xml as below

 <!-- ==================== Default Session Configuration ================= -->
  <!-- You can set the default session timeout (in minutes) for all newly   -->
  <!-- created sessions by modifying the value below.                       -->


<session-config>
        <session-timeout>60</session-timeout>
</session-config>

Mssql Authentication is highly preferable where possible. It allows you to conform with an existing windows domain already used at your workplace, and you don't have to know your user's passwords.

However, It seems that it would not be possible for use in the occasion that the server's machine does not authenticate to your local workplace's intranet.

If you use sql authentication, security will be entirely up to you.

If you use microsoft authentication, security is essentially taken care of for you, but you'll be dealing with additional restrictions.

}

ESC is the character _2_7, not _1_7. You can also try decimal 12 (aka. FF, form feed).

Note that all these special characters are not handled by the Arduino but by the program on the receiving side. So a standard Unix terminal (xterm, gnome-terminal, kterm, ...) handles a different set of control sequences then say a Windows terminal program like HTerm.

Therefore you should specify what program you are using exactly for display. After that it is possible to tell you what control characters and control sequences are usable.

If you navigate to where you have installed SQLExpress, e.g.

C:\Program Files\Microsoft SQL Server\110\Tools\Binn

You can run SQLLocalDB.exe and get a list of the all instances installed on your machine.

C:\Program Files\Microsoft SQL Server\110\Tools\Binn>SqlLocalDB.exe info
MSSQLLocalDB
ProjectsV12
v11.0

Then you can get further information on the instance.

C:\Program Files\Microsoft SQL Server\110\Tools\Binn>SqlLocalDB.exe info MSSQLLocalDB Name: MSSQLLocalDB
Version: 13.0.1601.5
Shared name:
Owner: Domain\User
Auto-create: Yes
State: Stopped
Last start time: 22/09/2016 10:19:33
Instance pipe name:

from msdn: public void Save (string filename); which is quite surprising to me because we dont just have to pass in the filename, we have to pass the filename along with the path for example: MyDirectory/MyImage.jpeg, here MyImage.jpeg does not actually exist yet, but our file will be saved with this name.

Another important point here is that if you are using Save() in a web application then use Server.MapPath() along with it which basically just returns the physical path for the virtual path which is passed in. Something like: image.Save(Server.MapPath("~/images/im111.jpeg"));

you are missing the "btn btn-navbar" section. For example:

        <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </a>

Generate the scripts?

Generate a script to create the table then generate a script to insert the data.

check-out SP_ Genereate_Inserts for generating the data insert script.

Note that if you rely on sleep taking exactly 50 ms, you won't get that. It will just be about it.

Yes the second syntax is fine.

Have you tried using the SPF wizard? https://www.spfwizard.net/

It can quickly generate basic and complex SPF records.

Works 100% without any problem and will not redirect to another page...I tried just copying this and changing your message

// Initialize a string and write Your message it will work
string message = "Helloq World";
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("alert('");
sb.Append(message);
sb.Append("');");
ClientScript.RegisterOnSubmitStatement(this.GetType(), "alert", sb.ToString());

to_timestamp()

You need to use to_timestamp() to convert your string to a proper timestamp value:

to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')

to_date()

If your column is of type DATE (which also supports seconds), you need to use to_date()

to_date('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')

Example

To get this into a where condition use the following:

select * 
from TableA 
where startdate >= to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
  and startdate <= to_timestamp('12-01-2012 21:25:33', 'dd-mm-yyyy hh24:mi:ss')

Note

You never need to use to_timestamp() on a column that is of type timestamp.

Using test

if test ! -z "$(docker images -q <name:tag>)"; then
  echo "Exist"
fi

or in one line

test ! -z "$(docker images -q <name:tag>)" &&  echo exist

As you can see, there are several ways to achieve this.

I personally use:

Expand all: CTRL + M + L

Collapse all: CTRL + M + O

Bonus:

Expand/Collapse on cursor location: CTRL + M + M

Another point of view (based on more fundamental mathematical topics)

The most general computing platform is a Turing Machine.

There is a problem with the Turing machine. All the input/output data stays inside the turing machine. In the real world there are input sources and output sinks external to our Turing machine, and in general governed by systems outside of our control. That is, those external system will send/receive data at will in any format with any desired data-scheduler.

Question: How do we manage to make independent turing-machines speak to each other in the most-general way so that each turing-machine sees their peers as either a source of input-data or sink of output-data?

Answer: Using something like camel, mule, BizTalk or any other ESB that abstract away the data handling between completing distinct "physical" (or virtual software) turing machines.

A little mathematical logic theory here:

"NOT a AND NOT b" is the same as "NOT (a OR b)", so:

"a NOT -1 AND b NOT -1" is equivalent of "NOT (a is -1 OR b is -1)", which is opposite (Complement) of "(a is -1 OR b is -1)".

So if you want exact opposite result, df1 and df2 should be as below:

df1 = df[(df.a != -1) & (df.b != -1)]
df2 = df[(df.a == -1) | (df.b == -1)]

If you don't have the option to delete the already existing file in the new location, but still need to move and delete from the original location, this renaming trick might work:

string newFileLocation = @"c:\test\Test\SomeFile.txt";

while (File.Exists(newFileLocation)) {
    newFileLocation = newFileLocation.Split('.')[0] + "_copy." + newFileLocation.Split('.')[1];
}
File.Move(@"c:\test\SomeFile.txt", newFileLocation);

This assumes the only '.' in the file name is before the extension. It splits the file in two before the extension, attaches "_copy." in between. This lets you move the file, but creates a copy if the file already exists or a copy of the copy already exists, or a copy of the copy of the copy exists... ;)

The deduplication (to select the max T1) and the aggregation need to be done as distinct steps. I've used a CTE since I think this makes it clearer:

;WITH sumCTE
AS
(
    SELECT  Rel.t2ID, SUM(Price) price
    FROM    @t1         AS T1
    JOIN    @relation   AS Rel 
    ON      Rel.t1ID=T1.ID
    GROUP 
    BY      Rel.t2ID
)
,maxCTE
AS
(
    SELECT  Rel.t2ID, Rel.t1ID, 
            ROW_NUMBER()OVER(Partition By Rel.t2ID Order By Price DESC)As PriceList
    FROM    @t1         AS T1
    JOIN    @relation   AS Rel 
    ON      Rel.t1ID=T1.ID
)
SELECT T2.ID AS T2ID
,T2.Name as T2Name
,T2.Orders
,T1.ID AS T1ID
,T1.Name As T1Name
,sumT1.Price
FROM    @t2 AS T2
JOIN    sumCTE AS sumT1
ON      sumT1.t2ID = t2.ID
JOIN    maxCTE AS maxT1
ON      maxT1.t2ID = t2.ID
JOIN    @t1 AS T1
ON      T1.ID = maxT1.t1ID
WHERE   maxT1.PriceList = 1

If you are targeting iOS 8+ you can use the new NSCalendar convenience methods to achieve this in a more terse format.

First create an NSCalendar and use whatever NSDate is required.

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDate *date = [NSDate date];

You could extract components individually via component:fromDate:

NSInteger year = [calendar component:NSCalendarUnitYear fromDate:date];
NSInteger month = [calendar component:NSCalendarUnitMonth fromDate:date];
NSInteger day = [calendar component:NSCalendarUnitDay fromDate:date];

Or, even more succinctly, use NSInteger pointers via getEra:year:month:day:fromDate:

NSInteger year, month, day;
[calendar getEra:nil year:&year month:&month day:&day fromDate:date];

For more information and examples check out NSDate Manipulation Made Easy in iOS 8. Disclaimer, I wrote the post.

So, there is a simple fix for this. It is admittedly awkward, but it works. xcopy will not prompt to find out if the destination is a directory or file IF the new file(filename) already exists. If you precede your xcopy command with a simple echo to the new filename, it will overwrite the empty file. Example

echo.>newfile.txt
xcopy oldfile.txt newfile.txt /Y

Try this:

$(function() {
    $("#type").change(function() {
        if ($(this).val() === 'parcel') $("#row_dim").show();
        else $("#row_dim").hide();
    }
}

You can add @RequestMapping like so:

@RequestMapping("/userGrid")
public @ResponseBody GridModel getUsersForGrid(
   @RequestParam("_search") String search,
   @RequestParam String nd,
   @RequestParam int rows,
   @RequestParam int page,
   @RequestParam String sidx) 
   @RequestParam String sord) {

I think all you have to do is ensure that the "__RequestVerificationToken" input is included in the POST request. The other half of the information (i.e. the token in the user's cookie) is already sent automatically with an AJAX POST request.

E.g.,

$("a.markAsDone").click(function (event) {
    event.preventDefault();
    $.ajax({
        type: "post",
        dataType: "html",
        url: $(this).attr("rel"),
        data: { 
            "__RequestVerificationToken":
            $("input[name=__RequestVerificationToken]").val() 
        },
        success: function (response) {
            // ....
        }
    });
});

According to the documentation it is changed,

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-sql.html

Example :

spring:
    datasource:
        url: 'jdbc:mysql://localhost/db?useSSL=false'
        username: root
        password: pass
        driver: com.mysql.jdbc.Driver
        hikari:
            minIdle: 10
            idle-timeout: 10000
            maximumPoolSize: 30

These are the following configuration changes we can do on hikari, please add/update according to your need.

autoCommit
connectionTimeout
idleTimeout
maxLifetime
connectionTestQuery
connectionInitSql
validationTimeout
maximumPoolSize
poolName
allowPoolSuspension
readOnly
transactionIsolation
leakDetectionThreshold

You can use HttpEntity to read both Body and Headers.

   @RequestMapping(value = "/restURL")
   public String serveRest(HttpEntity<String> httpEntity){
                MultiValueMap<String, String> headers = 
                httpEntity.getHeaders();
                Iterator<Map.Entry<String, List<String>>> s = 
                headers.entrySet().iterator();
                while(s.hasNext()) {
                    Map.Entry<String, List<String>> obj = s.next();
                    String key = obj.getKey();
                    List<String> value = obj.getValue();
                }
                
                String body = httpEntity.getBody();

    }

I am not very good in grep. But your problem can be solved using AWK command. Just see

awk '/select/,/from/' *.sql

The above code will result from first occurence of select till first sequence of from. Now you need to verify whether returned statements are having customername or not. For this you can pipe the result. And can use awk or grep again.

$this->db1->where('tennant_id', $tennant_id);
$this->db1->order_by('id', 'DESC');
return $this->db1->get('courses')->result();

You could use cjson, that claims to be up to 250 times faster than pure-python implementations, given that you have "some long complicated JSON file" and you will probably need to run it several times (decoders fail and report the first error they encounter only).

So, the trick here is to use absolute positioning calc like this:

top: calc(50% - XYpx);
left: calc(50% - XYpx);

where XYpx is half the size of your image, in my case, the image was a square. Of course, in this now obsolete case, the image must also change its size proportionally in response to window resize to be able to remain at the center without looking out of proportion.

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

I think using dtype where there is a name row is confusing the routine. Try

>>> r = np.genfromtxt(fname, delimiter=',', names=True)
>>> r
array([[  6.11882430e+02,   9.08956010e+03,   5.13300000e+03,
          8.64075140e+02,   1.71537476e+03,   7.65227770e+02,
          1.29111196e+12],
       [  6.11882430e+02,   9.08956010e+03,   5.13300000e+03,
          8.64075140e+02,   1.71537476e+03,   7.65227770e+02,
          1.29111311e+12],
       [  6.11882430e+02,   9.08956010e+03,   5.13300000e+03,
          8.64075140e+02,   1.71537476e+03,   7.65227770e+02,
          1.29112065e+12]])
>>> r[:,0]    # Slice 0'th column
array([ 611.88243,  611.88243,  611.88243])

I was having the same issue. Just avoid using an emulator with SDK 27. SDK 26 works fine!

What about cases where you want to reuse the name of a property, for example when throwing exception based on a property name, or handling a PropertyChanged event. There are numerous cases where you would want to have the name of the property.

Take this example:

switch (e.PropertyName)
{
    case nameof(SomeProperty):
    { break; }

    // opposed to
    case "SomeOtherProperty":
    { break; }
}

In the first case, renaming SomeProperty will change the name of the property too, or it will break compilation. The last case doesn't.

This is a very useful way to keep your code compiling and bug free (sort-of).

(A very nice article from Eric Lippert why infoof didn't make it, while nameof did)

This works from command line :

$ export LANG=en_US.UTF-8

None of the other answers above worked for me

    <VirtualHost *:80>
       DocumentRoot "what/ever/root/to/source"
       ServerName www.example.com

       <Directory "what/ever/root/to/source">
         Options FollowSymLinks MultiViews Includes ExecCGI
         AllowOverride All
         Order allow,deny
         allow from all
         <What Ever Rules You Need.>
      </Directory>

    </VirtualHost>

    <VirtualHost *:80>
      ServerName example.com
      ServerAlias *.example.com
      Redirect permanent / http://www.example.com/
    </VirtualHost>

This is what happens with the code above. The first virtual host block checks if the request is www.example.com and runs your website in that directory.

Failing which, it comes to the second virtual host section. Here anything other than www.example.com is redirected to www.example.com.

The order here matters. If you add the second virtualhost directive first, it will cause a redirect loop.

This solution will redirect any request to your domain, to www.yourdomain.com.

Cheers!

You should use abstract class to initialize a property. You can't inititalize in Inteface .

For use in a /etc/hosts file as a simple ad blocking technique to cause a domain to fail to resolve, the 0.0.0.0 address has been widely used because it causes the request to immediately fail without even trying, because it's not a valid or routable address. This is in comparison to using 127.0.0.1 in that place, where it will at least check to see if your own computer is listening on the requested port 80 before failing with 'connection refused.' Either of those addresses being used in the hosts file for the domain will stop any requests from being attempted over the actual network, but 0.0.0.0 has gained favor because it's more 'optimal' for the above reason. "127" IPs will attempt to hit your own computer, and any other IP will cause a request to be sent to the router to try to route it, but for 0.0.0.0 there's nowhere to even send a request to.

All that being said, having any IP listed in your hosts file for the domain to be blocked is sufficient, and you wouldn't need or want to also put an ipv6 address in your hosts file unless -- possibly -- you don't have ipv4 enabled at all. I'd be really surprised if that was the case, though. And still though, I think having the host appear in /etc/hosts with a bad ipv4 address when you don't have ipv4 enabled would still give you the result you are looking for which is for it to fail, instead of looking up the real DNS of say, adserver-example.com and getting back either a v4 or v6 IP.

You can initialize the System property in a static initializer:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:whereever/context.xml")
public class TestWarSpringContext {

    static {
        System.setProperty("myproperty", "foo");
    }

}

The static initializer code will be executed before the spring application context is initialized.

im not really that good at C , but i believe this code should get you complete single line till the end...

 #include<stdio.h>

 int main()   
{      
  char line[1024];    
  FILE *f=fopen("filename.txt","r");    
  fscanf(*f,"%[^\n]",line);    
  printf("%s",line);    
 }    

You can simply use the powerful .loc method and use one condition or several depending on your need (tested with pandas=1.0.5).

Code Summary:

df=pd.DataFrame(dict(Type='A B B C'.split(), Set='Z Z X Y'.split()))
df['Color'] = "red"
df.loc[(df['Set']=="Z"), 'Color'] = "green"

#practice!
df.loc[(df['Set']=="Z")&(df['Type']=="B")|(df['Type']=="C"), 'Color'] = "purple"

Explanation:

df=pd.DataFrame(dict(Type='A B B C'.split(), Set='Z Z X Y'.split()))

# df so far: 
  Type Set  
0    A   Z 
1    B   Z 
2    B   X 
3    C   Y

add a 'color' column and set all values to "red"

df['Color'] = "red"

Apply your single condition:

df.loc[(df['Set']=="Z"), 'Color'] = "green"


# df: 
  Type Set  Color
0    A   Z  green
1    B   Z  green
2    B   X    red
3    C   Y    red

or multiple conditions if you want:

df.loc[(df['Set']=="Z")&(df['Type']=="B")|(df['Type']=="C"), 'Color'] = "purple"

You can read on Pandas logical operators and conditional selection here: Logical operators for boolean indexing in Pandas

(4castle's answer is better than the below if you can assume Java >= 9)

You need to create a matcher and use that to iteratively find matches.

 import java.util.regex.Matcher;
 import java.util.regex.Pattern;

 ...

 List<String> allMatches = new ArrayList<String>();
 Matcher m = Pattern.compile("your regular expression here")
     .matcher(yourStringHere);
 while (m.find()) {
   allMatches.add(m.group());
 }

After this, allMatches contains the matches, and you can use allMatches.toArray(new String[0]) to get an array if you really need one.

You can also use MatchResult to write helper functions to loop over matches since Matcher.toMatchResult() returns a snapshot of the current group state.

For example you can write a lazy iterator to let you do

for (MatchResult match : allMatches(pattern, input)) {
  // Use match, and maybe break without doing the work to find all possible matches.
}

by doing something like this:

public static Iterable<MatchResult> allMatches(
      final Pattern p, final CharSequence input) {
  return new Iterable<MatchResult>() {
    public Iterator<MatchResult> iterator() {
      return new Iterator<MatchResult>() {
        // Use a matcher internally.
        final Matcher matcher = p.matcher(input);
        // Keep a match around that supports any interleaving of hasNext/next calls.
        MatchResult pending;

        public boolean hasNext() {
          // Lazily fill pending, and avoid calling find() multiple times if the
          // clients call hasNext() repeatedly before sampling via next().
          if (pending == null && matcher.find()) {
            pending = matcher.toMatchResult();
          }
          return pending != null;
        }

        public MatchResult next() {
          // Fill pending if necessary (as when clients call next() without
          // checking hasNext()), throw if not possible.
          if (!hasNext()) { throw new NoSuchElementException(); }
          // Consume pending so next call to hasNext() does a find().
          MatchResult next = pending;
          pending = null;
          return next;
        }

        /** Required to satisfy the interface, but unsupported. */
        public void remove() { throw new UnsupportedOperationException(); }
      };
    }
  };
}

With this,

for (MatchResult match : allMatches(Pattern.compile("[abc]"), "abracadabra")) {
  System.out.println(match.group() + " at " + match.start());
}

yields

a at 0
b at 1
a at 3
c at 4
a at 5
a at 7
b at 8
a at 10

This worked for me..

HTML:

<input type="radio" class="radioClass" name="radioName" value="1" />Test<br/>
<input type="radio" class="radioClass" name="radioName" value="2" />Practice<br/>
<input type="radio" class="radioClass" name="radioName" value="3" />Both<br/>

Jquery:

    $(".radioClass").each(function() {
        if($(this).is(':checked'))
        alert($(this).val());
    });

Hope it helps..

response.setContentType("text/html");

Above code would be include in "HTTP response" to inform the browser about the format of the response, so that the browser can interpret it.

Another RegEx-based solution (untested):

int NthIndexOf(string s, char t, int n) {
   if(n < 0) { throw new ArgumentException(); }
   if(n==1) { return s.IndexOf(t); }
   if(t=="") { return 0; }
   string et = RegEx.Escape(t);
   string pat = "(?<="
      + Microsoft.VisualBasic.StrDup(n-1, et + @"[.\n]*") + ")"
      + et;
   Match m = RegEx.Match(s, pat);
   return m.Success ? m.Index : -1;
}

This should be slightly more optimal than requiring RegEx to create a Matches collection, only to discard all but one match.

The only way to do it is by checking the value of the isCancelled() method and stopping playback when it returns true.

You need a development provisioning profile on your build machine. Apps can run on the simulator without a profile, but they are required to run on an actual device.

If you open the project in Xcode, it may automatically set up provisioning for you. Otherwise you will have to create go to the iOS Dev Center and create a profile.

It needs to go directly under the root <configuration> node and you need to set a path like this:

<?xml version="1.0"?>
<configuration>
    <location path="." inheritInChildApplications="false"> 
        <!-- Stuff that shouldn't be inherited goes in here -->
    </location>
</configuration>

A better way to handle configuration inheritance is to use a <clear/> in the child config wherever you don't want to inherit. So if you didn't want to inherit the parent config's connection strings you would do something like this:

<?xml version="1.0"?>
<configuration>
    <connectionStrings>
        <clear/>
        <!-- Child config's connection strings -->
    </connectionStrings>
</configuration>

You can get the script that SSMS provides by doing the following:

1. Right-click on a database in SSMS and choose delete
2. In the dialog, check the checkbox for "Close existing connections."
3. Click the Script button at the top of the dialog.

The script will look something like this:

USE [master]
GO
ALTER DATABASE [YourDatabaseName] SET  SINGLE_USER WITH ROLLBACK IMMEDIATE
GO
USE [master]
GO
DROP DATABASE [YourDatabaseName]
GO

you can use below code to know if current thread is UI/Main thread or not

if(Looper.myLooper() == Looper.getMainLooper()) {
   // Current Thread is Main Thread.
}

or you can also use this

if(Looper.getMainLooper().getThread() == Thread.currentThread()) {
   // Current Thread is Main Thread.
}

Like most JavaScript problems, there are many solutions. You could extend the Object that for better or worse works like many other languages' Dictionary (+ first class citizens). Nothing wrong with that, but another option is to construct a new Object that meets your specific needs.

function uberject(obj){
    this._count = 0;
    for(var param in obj){
        this[param] = obj[param];
        this._count++;
    }
}

uberject.prototype.getLength = function(){
    return this._count;
};

var foo = new uberject({bar:123,baz:456});
alert(foo.getLength());

all these solutions look like an overkill. Why use my solution?

previousElementSibling supported from IE9

document.addEventListener needs a polyfill

Please note i have chosen to return the first/last element in case boundaries are broken. In a RL usage, i would prefer it to return a null.

CREATE TABLE fractest( c1 TIME(3), c2 DATETIME(3), c3 TIMESTAMP(3) );

INSERT INTO fractest VALUES
('17:51:04.777', '2018-09-08 17:51:04.777', '2018-09-08 17:51:04.777');

You can use readfile and output the image headers which you can get from getimagesize like this:

$remoteImage = "http://www.example.com/gifs/logo.gif";
$imginfo = getimagesize($remoteImage);
header("Content-type: {$imginfo['mime']}");
readfile($remoteImage);

The reason you should use readfile here is that it outputs the file directly to the output buffer where as file_get_contents will read the file into memory which is unnecessary in this content and potentially intensive for large files.

If you are facing this issue and everything looks good, try invalidate cache/restart from your IDE. This will resolve the issue in most of the cases.

I just went through this issue and none of the suggestions solved my problem. While I was unable to start MySQL on boot and found the same message in the logs ("Another MySQL daemon already running with the same unix socket"), I was able to start the service once I arrived at the console.

In my configuration file, I found the following line: bind-address=xx.x.x.x. I randomly decided to comment it out, and the error on boot disappeared. Because the bind address provides security, in a way, I decided to explore it further. I was using the machine's IP address, rather than the IPv4 loopback address - 127.0.0.1.

In short, by using 127.0.0.1 as the bind-address, I was able to fix this error. I hope this helps those who have this problem, but are unable to resolve it using the answers detailed above.

You can choose a delimiter, in this case I chose a colon and printed the column number one, sorting by alphabetical order:

awk -F\: '{print $1|"sort -u"}' /etc/passwd

Use option -t for sendmail.

in your case - echo -e $mail | /usr/sbin/sendmail -t and add yout Recepient list to message itself like To: [email protected] [email protected] right after the line From:.....

-t option means - Read message for recipients. To:, Cc:, and Bcc: lines will be scanned for recipient addresses. The Bcc: line will be deleted before transmission.

As an addition to @C??? answer, make sure the title of the tooltip has not already been set manually in the HTML element. In my case, the span class for the tooltip already had a fixed tittle text, because of this my JQuery function $('[data-toggle="tooltip"]').prop('title', 'your new title'); did not work.

When I removed the title attribute in the HTML span class, the jQuery was working.

So:

<span class="showTooltip" data-target="#showTooltip" data-id="showTooltip">
      <span id="MyTooltip" class="fas fa-info-circle" data-toggle="tooltip" data-placement="top" title="this is my pre-set title text"></span>
</span>

Should becode:

<span class="showTooltip" data-target="#showTooltip" data-id="showTooltip">
      <span id="MyTooltip" class="fas fa-info-circle" data-toggle="tooltip" data-placement="top"></span>
</span>

using logback 1.1.3 I had to do the following (Scala code):

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".

Sub test()
    dbWb = Application.ActiveWorkbook.FullName
    dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2"  'Data2 is a named range


sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh

Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command

dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon

dbCommand.CommandText = sCommand
dbCommand.Execute

dbCon.Close

Arulx Z's answer was exactly what I was looking for.

I'm writing an app with Navigation Drawer with recyclerview and webviews, for keeping the web browsing inside the app regardless of hyperlinks clicked (thus not launching the external web browser). For that it will suffice to put the following 2 lines of code:

mWebView.setWebChromeClient(new WebChromeClient()); mWebView.setWebViewClient(new WebViewClient());?

exactly under your WebView statement.

Here's a example of my implemented WebView code:

public class WebView1 extends AppCompatActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    WebView wv = (WebView) findViewById(R.id.wv1); //webview statement
    wv.setWebViewClient(new WebViewClient());    //the lines of code added
    wv.setWebChromeClient(new WebChromeClient()); //same as above

    wv.loadUrl("http://www.google.com");
}}

this way, every link clicked in the website will load inside your WebView. (Using Android Studio 1.2.2 with all SDK's updated)

what i have experienced is that this exception raise when updating object have an id which not exist in table. if you read exception message it says "Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1" which means it was unable to found record with your given id.

To avoid this i always read record with same id if i found record back then i call update otherwise throw "exception record not found".

1. First make sure sa is enabled
2. Change the authontication mode to mixed mode (Window and SQL authentication)
3. Stop your SQL Server
4. Restart your SQL Server

If it's code running inside a loop that will likely cause an exception over and over again, then throwing exceptions is not a good thing, because they are pretty slow for large N. But there is nothing wrong with throwing custom exceptions if the performance is not an issue. Just make sure that you have a base exception that they all inherite, called BaseException or something like that. BaseException inherits System.Exception, but all of your exceptions inherit BaseException. You can even have a tree of Exception types to group similar types, but this may or may not be overkill.

So, the short answer is that if it doesn't cause a significant performance penalty (which it should not unless you are throwing a lot of exceptions), then go ahead.

It's because your statement does not produce output.

Besides all the warnings of Darin and lazy (they are right); the question still offerst something to learn.

If you want to execute methods that don't directly produce output, you do:

@{ Response.Redirect("~/Account/LogIn?returnUrl=Products");}

This is also true for rendering partials like:

@{ Html.RenderPartial("_MyPartial"); }

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

A handy base R option could be colMeans():

df[, colMeans(is.na(df)) != 1]

From the use of 8080 I'm assuming you are using a tomcat servlet container to serve your rest api. If this is the case you can also consider to have your webserver proxy the requests to the servlet container.

With apache you would typically use mod_jk (although there are other alternatives) to serve the api trough the web server behind port 80 instead of 8080 which would solve the cross domain issue.

This is common practice, have the 'static' content in the webserver and dynamic content in the container, but both served from behind the same domain.

The url for the rest api would be http://localhost/restws/json/product/get

Here a description on how to use mod_jk to connect apache to tomcat: http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html

You could do this:

verts = list(xrange(1000))

That would give you a list of 1000 elements in size and which happens to be initialised with values from 0-999. As list does a __len__ first to size the new list it should be fairly efficient.

I've found the best method is to write your default CSS for the older browsers, as older browsers including i.e. 5.5, 6, 7 and 8. Can't read @media. When I use @media I use it like this:

<style type="text/css">
    /* default styles here for older browsers. 
       I tend to go for a 600px - 960px width max but using percentages
    */
    @media only screen and (min-width: 960px) {
        /* styles for browsers larger than 960px; */
    }
    @media only screen and (min-width: 1440px) {
        /* styles for browsers larger than 1440px; */
    }
    @media only screen and (min-width: 2000px) {
        /* for sumo sized (mac) screens */
    }
    @media only screen and (max-device-width: 480px) {
       /* styles for mobile browsers smaller than 480px; (iPhone) */
    }
    @media only screen and (device-width: 768px) {
       /* default iPad screens */
    }
    /* different techniques for iPad screening */
    @media only screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:portrait) {
      /* For portrait layouts only */
    }

    @media only screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:landscape) {
      /* For landscape layouts only */
    }
</style>

But you can do whatever you like with your @media, This is just an example of what I've found best for me when building styles for all browsers.

iPad CSS specifications.

Also! If you're looking for printability you can use @media print{}

For completeness, in Numpy there are four maximum related functions. They fall into two different categories:

• np.amax/np.max, np.nanmax: for single array order statistics
• and np.maximum, np.fmax: for element-wise comparison of two arrays

I. For single array order statistics

NaNs propagator np.amax/np.max and its NaN ignorant counterpart np.nanmax.

• np.max is just an alias of np.amax, so they are considered as one function.

  >>> np.max.__name__
  'amax'
  >>> np.max is np.amax
  True
  

• np.max propagates NaNs while np.nanmax ignores NaNs.

  >>> np.max([np.nan, 3.14, -1])
  nan
  >>> np.nanmax([np.nan, 3.14, -1])
  3.14
  

II. For element-wise comparison of two arrays

NaNs propagator np.maximum and its NaNs ignorant counterpart np.fmax.

• Both functions require two arrays as the first two positional args to compare with.

  # x1 and x2 must be the same shape or can be broadcast
  np.maximum(x1, x2, /, ...);
  np.fmax(x1, x2, /, ...)
  

• np.maximum propagates NaNs while np.fmax ignores NaNs.

  >>> np.maximum([np.nan, 3.14, 0], [np.NINF, np.nan, 2.72])
  array([ nan,  nan, 2.72])
  >>> np.fmax([np.nan, 3.14, 0], [np.NINF, np.nan, 2.72])
  array([-inf, 3.14, 2.72])
  

• The element-wise functions are np.ufunc(Universal Function), which means they have some special properties that normal Numpy function don't have.

  >>> type(np.maximum)
  <class 'numpy.ufunc'>
  >>> type(np.fmax)
  <class 'numpy.ufunc'>
  >>> #---------------#
  >>> type(np.max)
  <class 'function'>
  >>> type(np.nanmax)
  <class 'function'>
  

And finally, the same rules apply to the four minimum related functions:

• np.amin/np.min, np.nanmin;
• and np.minimum, np.fmin.

Java versions before version 7 allow for these three combinations of try-catch-finally...

try - catch
try - catch - finally
try - finally

finally block will be always executed no matter of what's going on in the try or/and catch block. so if there is no catch block, the exception won't be handled here.

However, you will still need an exception handler somewhere in your code - unless you want your application to crash completely of course. It depends on the architecture of your application exactly where that handler is.

• Java try block must be followed by either catch or finally block.
• For each try block there can be zero or more catch blocks, but only one finally block.
• The finally block will not be executed if program exits(either by calling System.exit() or by causing a fatal error that causes the process to abort).

PowerShell will actually treat any comma-separated list as an array:

"server1","server2"

So the @ is optional in those cases. However, for associative arrays, the @ is required:

@{"Key"="Value";"Key2"="Value2"}

Officially, @ is the "array operator." You can read more about it in the documentation that installed along with PowerShell, or in a book like "Windows PowerShell: TFM," which I co-authored.

If you mean you want to open a new tab, try the below:

protected void Page_Load(object sender, EventArgs e)
{
    this.Form.Target = "_blank";
}

protected void Button1_Click(object sender, EventArgs e)
{

    Response.Redirect("Otherpage.aspx");
}

This will keep the original page to stay open and cause the redirects on the current page to affect the new tab only.

You may have to perform a diff and put document.getElementById('name') code inside a condition, in case your component is something like this:

// using the new hooks API
function Comp(props) {
  const { isLoading, data } = props;
  useEffect(() => {
    if (data) {
      var name = document.getElementById('name').value;
    }
  }, [data]) // this diff is necessary

  if (isLoading) return <div>isLoading</div>
  return (
    <div id='name'>Comp</div>
  );
}

If diff is not performed then, you will get null.

value ^= true;

That is value xor-equals true, which will flip it every time, and without any branching or temporary variables.

There is more than one way to define "memory leak". In particular, there are two primary definitions of "memory leak" that are in common usage among programmers.

The first commonly used definition of "memory leak" is, "Memory was allocated and was not subsequently freed before the program terminated." However, many programmers (rightly) argue that certain types of memory leaks that fit this definition don't actually pose any sort of problem, and therefore should not be considered true "memory leaks".

An arguably stricter (and more useful) definition of "memory leak" is, "Memory was allocated and cannot be subsequently freed because the program no longer has any pointers to the allocated memory block." In other words, you cannot free memory that you no longer have any pointers to. Such memory is therefore a "memory leak". Valgrind uses this stricter definition of the term "memory leak". This is the type of leak which can potentially cause significant heap depletion, especially for long lived processes.

The "still reachable" category within Valgrind's leak report refers to allocations that fit only the first definition of "memory leak". These blocks were not freed, but they could have been freed (if the programmer had wanted to) because the program still was keeping track of pointers to those memory blocks.

In general, there is no need to worry about "still reachable" blocks. They don't pose the sort of problem that true memory leaks can cause. For instance, there is normally no potential for heap exhaustion from "still reachable" blocks. This is because these blocks are usually one-time allocations, references to which are kept throughout the duration of the process's lifetime. While you could go through and ensure that your program frees all allocated memory, there is usually no practical benefit from doing so since the operating system will reclaim all of the process's memory after the process terminates, anyway. Contrast this with true memory leaks which, if left unfixed, could cause a process to run out of memory if left running long enough, or will simply cause a process to consume far more memory than is necessary.

Probably the only time it is useful to ensure that all allocations have matching "frees" is if your leak detection tools cannot tell which blocks are "still reachable" (but Valgrind can do this) or if your operating system doesn't reclaim all of a terminating process's memory (all platforms which Valgrind has been ported to do this).

Your question is already answered here :

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Also, a good link on what happens if we try to include our class file in rt.jar.

Java 8 Solution: I just had this problem and solved it by adding the remote site's certificate to my Java keystore. My solution was based on the solution at the myshittycode blog, which was based on a previous solution in mykong's blog. These blog article solutions boil down to downloading a program called InstallCert, which is a Java class you can run from the command line to obtain the certificate. You then proceed to install the certificate in Java's keystore.

The InstallCert Readme worked perfectly for me. You just need to run the following commands:

1. javac InstallCert.java
2. java InstallCert [host]:[port] (Enter the given list number of the certificate you want to add in the list when you run the command - likely just 1)
3. keytool -exportcert -alias [host]-1 -keystore jssecacerts -storepass changeit -file [host].cer
4. sudo keytool -importcert -alias [host] -keystore [path to system keystore] -storepass changeit -file [host].cer

See the referenced README file for an example if need be.

I had this problem and it was because another script was deleting all of the tables and recreating them, but my table wasn't being recreated. I spent ages on this issue before I noticed that my table wasn't even visible on the page. Can you see your table before you initialize DataTables?

Essentially, the other script was doing:

let tables = $("table");
for (let i = 0; i < tables.length; i++) {
  const table = tables[i];
  if ($.fn.DataTable.isDataTable(table)) {
    $(table).DataTable().destroy(remove);
    $(table).empty();
  }
}

And it should have been doing:

let tables = $("table.some-class-only");
... the rest ...

Try it ..

UPDATE PRODUCTION a
SET (name, count) = (
SELECT name, count
        FROM STAGING b
        WHERE a.ID = b.ID)
WHERE EXISTS (SELECT 1
    FROM STAGING b
    WHERE a.ID=b.ID
 );

Create a fake update to enforce the rowlock.

UPDATE <tablename> (ROWLOCK) SET <somecolumn> = <somecolumn> WHERE id=1

If that's not locking your row, god knows what will.

After this "UPDATE" you can do your SELECT (ROWLOCK) and subsequent updates.

Using the flag -Command you can execute your entire powershell line as if it was a command in the PowerShell prompt:

powershell -Command "& '<PATH_TO_PS1_FILE>' '<ARG_1>' '<ARG_2>' ... '<ARG_N>'"

This solved my issue with running PowerShell commands in Visual Studio Post-Build and Pre-Build events.

select TABLE_NAME from user_tables;

Above query will give you the names of all tables present in that user;

Thanks to autocomplete. I got lucky after a few hit and trials:

    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    card_view:backgroundTint="@color/whicheverColorYouLike"

-- or -- (both are basically the same thing)

    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:backgroundTint="@color/whicheverColorYouLike"

This worked for me on API Version 17 with design library 23.1.0.

In my case it was a global .gitignore, as explained in @HankCa's answer.

Instead of forcefully adding the jar, which you'll need to remember to do in each Gradle project, I added an override to re-include the wrapper jar in my global .gitignore:

*.jar
!gradle/wrapper/gradle-wrapper.jar

This is useful to me as I have many projects that use Gradle; Git will now remind me to include the wrapper jar.

This override will work so long as no directories above gradle-wrapper.jar (such as gradle and wrapper) are ignored -- git will not descend in to ignored directories for performance reasons.

Instead, just do a hook_form_alter and make the button an image button and you are done!

Remove *%,&@! from below string:

s = "this is my string,  and i will * remove * these ** %% "
new_string = s.translate(s.maketrans('','','*%,&@!'))
print(new_string)

# output: this is my string  and i will  remove  these  

I faced same issue , I just deleted the remote branch and created new branch from the master and merged my changes from old feature branch to new feature branch . Now i tried pull and push requests its worked for me

Make sure you're doing this for a good reason, a simple function like the following would allow static typing and allows your IDE to do things like "Find References" and Refactor -> Rename.

public Task <T> factory (String name)
{
  Task <T> result;

  if (name.CompareTo ("A") == 0)
  {
    result = new TaskA ();
  }
  else if (name.CompareTo ("B") == 0)
  {
    result = new TaskB ();
  }

  return result;
}

You need Java 8 to get a multiple inheritance problem, but it is still not a diamon problem as such.

interface A {
    default void hi() { System.out.println("A"); }
}

interface B {
    default void hi() { System.out.println("B"); }
}

class AB implements A, B { // won't compile
}

new AB().hi(); // won't compile.

As JB Nizet comments you can fix this my overriding.

class AB implements A, B {
    public void hi() { A.super.hi(); }
}

However, you don't have a problem with

interface D extends A { }

interface E extends A { }

interface F extends A {
    default void hi() { System.out.println("F"); }
}

class DE implement D, E { }

new DE().hi(); // prints A

class DEF implement D, E, F { }

new DEF().hi(); // prints F as it is closer in the heirarchy than A.
